Is the 4 Nozzle Kit for the DJI T100 worth it?

DJI Agras T100: 2-Nozzle vs. 4-Nozzle Setup – Which Delivers More for Your Operation?

In the fast-evolving world of agricultural drones, the DJI Agras T100 stands out as a powerhouse for large-scale spraying. With its massive 100L (26.4-gallon) tank and impressive lift capacity, one of the most common questions we hear from custom applicators is: “Should I stick with the standard 2-nozzle setup or upgrade to the optional 4-nozzle package?”

Here’s a clear, practical breakdown to help you decide.

Flow Rate Comparison: The Numbers That Matter

The biggest difference comes down to maximum flow rate (how much liquid you can put down per minute):

• Standard 2-Nozzle Setup: 30 L/min ≈ 7.9 gallons per minute (GPM)
• Optional 4-Nozzle Setup (Mist Nozzle Package): 40 L/min ≈ 10.6 GPM

That’s roughly a 33–34% increase in spraying capacity with the 4-nozzle upgrade.

When to Choose 2 Nozzles (Standard)

• Field crops with moderate application rates (e.g., 2–4 GPA)
• Excellent droplet uniformity and coverage with standard nozzles
• Slightly lighter weight (75 kg spraying configuration)
• Simpler setup and maintenance
• Ideal for most row-crop and broad-acre operations where 7.9 GPM meets your needs

Real-world testing shows the 2-nozzle config handles many common tasks efficiently, especially when paired with optimal flight speeds and swath widths.

When to Choose 4 Nozzles (Upgrade)

• Higher application rates (5+ GPA) or thicker canopies
• Orchard, vineyard, or specialty crops needing better penetration (mist nozzles shine here)
• Faster ground speeds without sacrificing coverage
• Maximum productivity — up to 70+ acres per hour reported in ideal conditions
• The extra nozzles (adding two mist-style) + wider nozzle spacing (up to 1834 mm outermost) improve downwash and droplet distribution in dense foliage

The 4-nozzle package pushes the dual impeller pumps harder for that extra throughput, making it a game-changer for high-volume work.

Real-World Performance Impact

• Higher flow = ability to fly faster or apply more product per pass → fewer refill stops and more acres per day.
• Battery life, flight time, and overall efficiency improve when matching flow rate to your target GPA.
• Users report noticeable gains in dense crops or when pushing 4 GPA+ rates, where the standard setup hits its flow limit.

Other Considerations

• Weight: 4-nozzle adds a small amount (~2 kg).
• Droplet size: Still adjustable (50–500 μm) with both setups.
• Cost: The mist nozzle package is an optional upgrade — contact us for current pricing and availability.
• Maintenance: More nozzles mean slightly more parts to inspect, but DJI’s design keeps it straightforward.

Which One Is Right for Your Farm?

For most large-scale row-crop applicators in Utah and surrounding states, the standard 2-nozzle gets the job done efficiently. If you run orchards, need higher GPA rates, or want maximum throughput for tight spray windows, the 4-nozzle upgrade delivers clear ROI.

At Avary Drone, we help custom applicators choose the right configuration, provide full training (Part 107/137), and offer turnkey packages including the T100, Drone Cone mixing systems, and support for FAA compliance.
